Nothing! To enter the pool, simply provide your name or phone number to the lifeguard at the pool check-in desk. He/she will check your photo, make sure that you have been validated and then check you in. Each member must have a valid membership in order to gain access to the pool. If you created a PIN for your account, you will be prompted to enter your PIN before finishing the check-in process. *There may be instances where the lifeguards may request to see your valid account from your phone or a purchase confirmation email due to internet outages in the area, but cases like these will be rare*
